How to distinguish the quality of aluminum alloy cables

Conductor, insulation and armored sheath are necessary for the composition of aluminum alloy cables. The quality of aluminum alloy cables mainly depends on the aluminum alloy conductor rods and cable insulation. Aluminum alloy cables have very good performance, corrosion resistance, and mechanical Performance, bending performance, flexibility, etc. 1. Aluminum alloy conductor rod See if we … Read more

Is it better to use ordinary wires for household decoration or flame retardant wires?

Regarding this problem, it has always been a problem that owners have struggled with during decoration. Although each has its own advantages, it is recommended to use flame-retardant wires and higher safety performance when conditions permit. The advantages of flame-retardant wires: in the event of a fire, the flame spread speed can be controlled within … Read more

The main functions and advantages of ACSR

在先进科学技术的现代时代,许多现代工业设施已经出现在我们的世界中并存在于我们的生活中。钢芯铝绞线也是在电力中起重要作用的主要力量。ACSR是由单层或多层铝绞线在镀锌钢芯外部绞合而成的增强钢丝。内部是钢“芯”,外部通过绞合用铝线包裹在钢芯上。; 钢芯主要用于增加强度,铝绞线主要用于传输电能。它在电力和输电线路行业中占有重要地位。对于高压传输线,由于线路的路径有限,因此无法将其安装在一条路径上。对于多行,人们想出了一种使用一条路径,一组铁塔和多根电线的方法,即一条线相当于多条线。对于500KV输电线路,我国大部分地区采用悬挂四根电线的方法。这种接线方法称为同塔并联。这就是为什么某些杆用于“ L J”和“ LGJ”的主要原因。 下面简要介绍一下ACSR的优点和应用。该ACSR具有结构简单,安装,维修方便,低线成本,传输容量大,并且有利于特殊地理条件如杂交河流和沟壑铺设。它具有出色的导电性以及令人满意的机械强度和拉伸强度。高强度和可扩展的塔杆间距等功能。因此,广泛用于各种电压等级的架空输配电线路。 钢芯铝绞线的缩写:“ LGJ”是绞合的铝线和钢丝,普通铝绞线“ L J”主要用于架空输电线路。ACSR的内部为钢“芯”,外部通过绞合用铝线包裹在钢芯上。钢芯主要增加强度,而铝绞线主要传输电能。它们都是裸线,用途基本相同,型号规格不同。 普通铝绞线:型号以“ L J”表示,为裸线。目前,中国一般使用铝包钢绞线(LGJ)作为导体。钢芯主要用于增加强度,铝绞线主要用于传输电能。根据电压的不同,导线的截面积也不同。例如,500 kV传输线的电流导体通常使用LGJ-400 / 35导体。其中,L是铝线的缩写,G是钢芯的缩写,J是绞线的缩写,400是铝的400平方毫米,而35是钢的35平方毫米。

How to distinguish between national standard wires and inferior non-standard wires

Before moving into a new house, everyone will check the house first, but most citizens will focus on the structure of the house, and they rarely care about the wires inside the walls. If the house is compared to a person, then the wires hidden in the walls are the vital “arteries”. The wires for … Read more

Wire and cable products are mainly divided into five categories
